| IRF3

Interferon regulatory factor 3, also known as IRF3, is an interferon regulatory factor.IRF3 is a member of the interferon regulatory transcription factor (IRF) family. IRF3 was originally discovered as a homolog of IRF1 and IRF2. IRF3 has been further characterized and shown to contain several functional domains including a nuclear export signal, a DNA-binding domain, a C-terminal IRF association domain and several regulatory phosphorylation sites. IRF3 is found in an inactive cytoplasmic form that upon serine/threonine phosphorylation forms a complex with CREBBP. The complex translocates into the nucleus for the transcriptional activation of interferons alpha and beta, and further interferon-induced genes.
 

| Typical data

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, wash technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data are provided below for reference only.

| Repeatability

Intra-assay Precision (Precision within an assay)：CV% < 10%; Inter-assay Precision (Precision between assays)：CV% < 10%
 

| Recovery

The recovery of Mouse IRF3 spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Tissue Homogenates(n=8)	84-102	96
Cell Lysates(n=8)	96-108	105

 

| Linearity

Samples were spiked with high concentrations of Mouse IRF3 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Tissue Homogenates(n=4)	Cell Lysates(n=4)
1 : 2	Range (%)	84-95	90-110
	Average (%)	90	95
1 : 4	Range (%)	89-103	105-114
	Average (%)	94	107
